This implements support for DPI output using the port node in the device tree to connect a DPI LCD display to the MCDE. The block also supports TV-out but we leave that for another day when we have a hardware using it. We implement parsing and handling of the "port" node, and follow that to the DPI endpoint. The clock divider used by the MCDE to divide down the "lcdclk" (this has been designed for TV-like frequencies) is represented by an ordinary clock provider internally in the MCDE. This idea was inspired by the PL111 solution by Eric Anholt: the divider also works very similar to the Pl111 clock divider. We take care to clear up some errors regarding the number of available formatters and their type. We have 6 DSI formatters and 2 DPI formatters. Tested on the Samsung GT-I9070 Janice mobile phone.

To be able to support DPI without messing things up we first break out the DSI set-up to a separate function. Signed-off-by:

I was confused when the graphics came out with blue penguins on the DPI panel. It turns out that the so-called "packed RGB666" mode on the DSI formatter is incorrect: this mode is the actual RGB888 mode, and the mode called RGB888 is BGR888. The claims that the MCDE had inverse RGB/BGR buffer formats was wrong, so correct this and the buggy register and everything is much more consistent, and graphics look good on all targets, both DPI and DSI.

While the system heap can return non-contiguous pages, try to allocate larger order pages if possible. This will allow slight performance gains and make implementing page pooling easier.

This patch is basically a port of Ørjan Eide's similar patch for ION https://lore.kernel.org/lkml/20200414134629.54567-1-orjan.eide@arm.com/ Only sync the sg-list of dma-buf heap attachment when the attachment is actually mapped on the device. dma-bufs may be synced at any time. It can be reached from user space via DMA_BUF_IOCTL_SYNC, so there are no guarantees from callers on when syncs may be attempted, and dma_buf_end_cpu_access() and dma_buf_begin_cpu_access() may not be paired. Since the sg_list's dma_address isn't set up until the buffer is used on the device, and dma_map_sg() is called on it, the dma_address will be NULL if sync is attempted on the dma-buf before it's mapped on a device. Before v5.0 (commit 55897af6 ("dma-direct: merge swiotlb_dma_ops into the dma_direct code")) this was a problem as the dma-api (at least the swiotlb_dma_ops on arm64) would use the potentially invalid dma_address. How that failed depended on how the device handled physical address 0. If 0 was a valid address to physical ram, that page would get flushed a lot, while the actual pages in the buffer would not get synced correctly. While if 0 is an invalid physical address it may cause a fault and trigger a crash. In v5.0 this was incidentally fixed by commit 55897af6 ("dma-direct: merge swiotlb_dma_ops into the dma_direct code"), as this moved the dma-api to use the page pointer in the sg_list, and (for Ion buffers at least) this will always be valid if the sg_list exists at all. But, this issue is re-introduced in v5.3 with commit 449fa54d ("dma-direct: correct the physical addr in dma_direct_sync_sg_for_cpu/device") moves the dma-api back to the old behaviour and picks the dma_address that may be invalid. dma-buf core doesn't ensure that the buffer is mapped on the device, and thus have a valid sg_list, before calling the exporter's begin_cpu_access.

In preparation for some patches to optmize the system heap code, rework the dmabuf exporter to utilize sgtables rather then pageslists for tracking the associated pages. This will allow for large order page allocations, as well as more efficient page pooling. In doing so, the system heap stops using the heap-helpers logic which sadly is not quite as generic as I was hoping it to be, so this patch adds heap specific implementations of the dma_buf_ops function handlers.

The init sequence consist of a number of unknown settings for the display controller. This patch achieves two things: - Fix an error that must have happened when the driver was converted from the backlight subsystem: the 0xb8 configuration command was lost and added as a tail to the previous command. - Update some minor settings in some bytes here and there according to changes in the Samsung GT-I9070 and Samsung GT-S7710 code dumps. Since two other devices use these settings they probably reflect trimmings later found to be better for the display rather than customizations for these devices. Signed-off-by:
